I’m currently working on a senior project using the LoRa E5 Mini board to transmit notifications to TTN. I was testing with the sample code provided in the Seeed Studio Github repository, linked below. The code works fine but I was wanting to customize it to only send 1 single message to TTN when a UART interrupt is detected. I was also curious as to where the payload data is written and if I could edit this somehow, but this isn’t a crucial detail. My main point of confusion lies in where exactly I need to insert or edit code to accomplish this so any pointers/guidance you guys have would be really appreciated. Thanks!
